HMS M2 + drift

Built by Vickers in 1912, this 296ft submarine is classified as a war grave due to the fact that she sank as the result of an accident on the 26th January 1932 killing all hands. The M2 was unique in that she carried a small aircraft in a hanger built on to the conning tower and it is thought that whilst practising emergency diving the hangar door was not properly closed, quickly flooding the ship and sending her to the bottom.
She is an amazing dive virtually intact apart from the crane for aircraft recovery having been trawled off a few years ago and some clandestine salvage, which saw the removal of her propellers. The conning tower rises to a height of 9m above the sea bed, and jib of the winch is still visible in the open hanger. Distance from Weymouth 13 miles.
